Impact of Mating Frequency on Reproductive Success of Spodoptera frugiperda (Lepidoptera: Noctuidae)
Year: 2024
Type: article
Abstract: This study investigates the influence of mating frequency on the reproductive success of Spodoptera frugiperda, a significant agricultural pest. We compared the effects of single and multiple matings on fecundity and hatching percentage using laboratory-reared moths. Females subjected to multiple matings exhibited significantly higher fecundity and improved hatching success compared to single-mated females. Specifically, multiple-mated females produced an average of 1468.6 eggs with a hatching percentage of 88.8%, while single-mated females produced 858 eggs with a hatching percentage of 78.4%. These results are consistent with the hypothesis that multiple mating provides nutritional and genetic benefits, enhancing reproductive output and offspring viability. The study highlights the role of mating frequency in shaping reproductive performance and suggests potential applications for pest management strategies. By targeting mating behaviors, such as through mating disruption or sterilization, it may be possible to mitigate the impact of S. frugiperda on crops. This research contributes to our understanding of the reproductive dynamics of this pest and offers insights for developing more effective pest control measures.
